Automated seamline construction for high-quality high-resolution orthomosaics

Abstract

A system for semi-automated feature extraction comprising an image analysis server that receives and initializes a plurality of raster images, a feature extraction server that identifies and extracts image features, a mosaic server that assembles mosaics from multiple images, and a rendering engine that provides visual representations of images for review by a human user, and a method for generating a cost raster utilizing the system of the invention.

What is claimed is: 
     
       1. A method for creating seamlines in orthomosaic imagery using a cost, comprising the steps of:
 receiving, at an image analysis server, a plurality of input images; 
 identifying, using a feature extraction server, a plurality of linear image features within the plurality of input images; 
 computing a cost raster based at least in part on at least a portion of the plurality of image features identified; 
 automatically generating seamlines along at least some of the linear image features using cost minimization; and 
 vectorizing the generated seamlines.
